Faced with a large crowd of demonstrators who'd broken past police barriers outside the Hyatt Regency hotel in Burlingame, Trump and his retinue were seen hopping over a highway median to enter through a back door.

"It felt like I was crossing the border, actually," Trump said at the start of his speech, according to Politico.

Trump exited the hotel in the same way, hopping up and over the barrier to return to his motorcade.
